"All of us at Oni Press were saddened to have learned of the passing of our friend and colleague, Eduardo Barreto," said the publisher.

"It was our absolute pleasure to have the opportunity to collaborate with this great artist. Eduardo fit the classic model of a working illustrator, and he particularly loved the wide variety of comics that he read growing up in Uruguay.

"Those who worked with him remember him as a true professional, and everyone who met him could instantly call him a friend. Eduardo Barreto leaves behind a tremendous body of work, as well as a legion of fans, all of whom will miss him dearly. We join them in extending our deepest condolences to his family for their loss."

Barreto is survived by his colourist daughter Andrea and son Diego, who has worked on BOOM! Studios' Irredeemable.
